[00:04:35] <furrywolf> manual makes it sound like there is indeed a gib... it must only be visible from the bottom. I didn't try crawling under the knee. heh.
[00:25:15] <archivist> furrywolf, has it been outside and got rusty? or if like mine is the brake on
[00:26:03] <archivist> there is a bolt that grips the gib to brake it
[00:27:49] <archivist> on some axes it is a small handle
[00:29:06] <archivist> actually the brakes are just visible in http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=8909&subject=25697
[00:29:40] <shogunx> Hi all. any hardware recommendations for a table top mill for pcb etching purposes?
[00:31:14] <archivist> a good high speed spindle, ball screws(no backlash)
[00:32:21] <archivist> a reasonably flat place to mount the pcbs, (mill it flat)
[00:32:33] <shogunx> 3 axis is sufficient for this application, i would presume?
[00:32:40] <archivist> yes
[00:33:09] <furrywolf> brake is off. no rust on ways.
[00:33:29] <shogunx> usb<-->parallel port conversion device will work ok with emc?
[00:33:30] <furrywolf> brake is a handle that sticks out under the knee on mine
[00:33:35] <furrywolf> shogunx: no
[00:33:55] <flyback> shogunx, if it does proper bidirectional gpio probably
[00:34:00] <flyback> unfortunitely most don't
[00:34:36] <furrywolf> USB is not suitable for realtime machine control. the conclusion we've reached is any product claiming otherwise is spouting crap. If you're controlling anything pointier than a 3d glue gun, don't use any usb products.
[00:34:42] <shogunx> a sufficient number of regular old gpio pins would work tho, like say, on a cubieboard?
[00:35:24] <flyback> furrywolf, I don't agree with you there but gpio to parallel port adaptors are usually ick for anything but a printer
[00:35:25] <shogunx> or do i need to dust off an x86 box with a dedicated parallel port to accomplish this job correctly?
[00:35:31] <flyback> but there's plenty of proper usb gpio stuff
[00:35:34] <flyback> shogunx,
[00:35:40] <flyback> get a pci-e parallel port card
[00:35:45] <flyback> $10?
[00:36:20] <shogunx> most of my network here is ARM based these days. i have no such slot, but i will see if i can hunt down a board that has one.
[00:36:55] <shogunx> the only x86 around are some old laptops and 1U servers that got replaced.
[00:37:05] <flyback> but you are right
[00:37:11] <flyback> something with decent gpio might work good
[00:37:32] <flyback> suggestion use some kind of good faster buffer chip with good surge protection
[00:38:25] <furrywolf> you will need to write your own drivers to do something like that. probably not good for a first project.
[00:38:52] <shogunx> hmm... would require a kernel compile for the real time extensions, and presumably some code to work with general gpio pins, and recompile on emc for armhf as well.
[00:38:55] <shogunx> complex.
[00:39:00] <furrywolf> Mesa sells ethernet motion control boards if you don't have a parallel port, which also offers a lot more i/o and better performance.
[00:39:07] <flyback> I am sure someone as writtena shim
[00:39:20] <furrywolf> linuxcnc on arm works, but has performance issues, from what I've heard.
[00:39:34] <furrywolf> and, again, you'll be on your own for drivers.
[00:39:47] <shogunx> i have some beefy arms. these allwinner A80 big.little 8 core machines do well.
[00:39:55] <flyback> mmm
[00:40:15] <flyback> big.little was freaking genius btw
[00:40:53] <shogunx> so... get an x86 with pci-e and a port sounds like the path of least resistance, eh?
[00:42:02] <furrywolf> yes. :)
[00:42:29] <shogunx> yeah, the big.little rocks.
[00:42:36] <furrywolf> or a board with a parallel port. a lot of single board solutions have them.
[00:42:37] <furrywolf> or use a Mesa ethernet board.
[00:42:39] <flyback> anyone here dealing with legacy cnc gear with floppy drives?
[00:42:39] <shogunx> any particular vendor of mills recommended?
[00:42:40] <flyback> yeah I know what the channel is but I am sure some of you work in the field and deal with it
[00:43:26] <furrywolf> shogunx: how big? :P
[00:47:38] <shogunx> 200mm ^2 or that range
[00:47:38] <furrywolf> tiny
[00:47:38] <furrywolf> Sherline is nice
[00:50:24] <furrywolf> bbl, wolfy bedtime
[00:55:28] <shogunx> hey, thanks, folks. i appreciate it.
[00:56:38] <furrywolf> most people are already asleep, try tomorrow during normal people-in-the-US-being-awake hours. :)
[00:56:48] <furrywolf> bbl
[00:59:56] <shogunx> aye
[01:20:03] <CaptHindsight> shogunx: the old cubieboards have the A10 or A20 they might work since they have integrated Ethernet
[01:20:30] <CaptHindsight> it was a paint to get an open non magic tool chain working on them
[01:21:30] <CaptHindsight> and the other missing piece is open drivers for openGL
[02:01:13] <pink_vampire> night
[02:02:08] <archivist> zeeshan|2, this is near you fleabay 190808002823
[02:02:32] <archivist> but all mine :)
[02:03:04] <pink_vampire> I've finish today the back for the band saw
[02:08:19] <Deejay> moin
[02:13:06] <pink_vampire> morning :)
[02:13:12] <pink_vampire> I've finish today the back for the band saw
[02:21:11] <fenn> pink_vampire: i just found a good design for a portable bandsaw stand: http://www.trick-tools.com/Femi-782XL-Yellow-Benchtop-Mitering-Bandsaw-HEM-Saw-Racing-Edition-8946 http://www.trick-tools.com/Vertical_Table_for_Femi_782_Bandsaw_F_707512_000_00_2210
[02:23:04] <pink_vampire> fenn: same here,,
[02:23:06] <fenn> notice that the pivot is inline with the backplate of the vise so the blade is always close
[02:23:52] <pink_vampire> I'm goint to mount it in 45 deg fix,
[02:24:45] <pink_vampire> http://www.homedepot.com/p/Everbilt-4-1-2-in-Satin-Chrome-Ball-Bearing-Hinge-15487/202033815
[02:25:21] <pink_vampire> almost zero backlash
[02:26:11] <fenn> that's pretty cheap
[02:28:23] <pink_vampire> I've also got 2 cart wheels
[02:45:38] <flyback> pink_vampire, nice creative nick
[03:21:57] * Wolf_ yawns
[03:24:40] <Wolf_> adjusting the gibs on my machine did wonders for it, mostly, hand wheels still suck… but got it down to less then .0005” of play in the x/y each and could still push the axis in each direction with 2 fingers
[04:39:59] <XXCoder> yo
[04:40:33] <XXCoder> pink_vampire: ball bearing interesting
[06:13:23] <pink_vampire> I see some daylight - going to sleep.
[06:14:28] <Loetmichel> hrrrmpf. thats a first... just searched why the Fo-nic here cant talk with the swicht... turned out i used an ST feedthru thingy that has missing its ferrule inside (so te two st plugs dont aling)... and i picked it fresh fro,m the package, not a used one :-(
[06:16:03] <Loetmichel> two hours dwon the drain for a 50 cent part... :-(
[06:42:30] <pink_vampire> Loetmichel: why? what kind of part?
[07:01:41] <Loetmichel> pink_vampire: http://shop.jacob-computer.de/lwl-kupplung-st-st-90700-artnr-294227.html
[07:02:31] <pink_vampire> Loetmichel: you made something like that?
[07:03:55] <Loetmichel> i made a PC... wiht this on the back for feeding the fiber optic network thru
[07:04:27] <Loetmichel> and one of the two feedthrus had missing a "caliber" ferrule inside that alings the two fiber ends to each other
[07:04:40] <Loetmichel> took me a while to find that fault
[07:05:30] <Loetmichel> i never suspected te feedthru
[07:05:59] <Loetmichel> i spwapped the FO nic, i spapped the fibre pigtails... i thought the driver may have an error
[07:06:07] <Loetmichel> but i never thought of that tiny thing
[07:09:19] <pink_vampire> I can't stay awake.. have to sleep :(
[07:09:39] <pink_vampire> 7:46AM
[07:09:51] <Loetmichel> <- just had dinner
[07:10:02] <Loetmichel> [13:46] <Loetmichel> <- just had dinner
[07:10:11] <Loetmichel> at work
[07:10:24] <pink_vampire> me too.
[07:10:26] <Loetmichel> starting to get that "after eating sleepyness"
[07:10:39] <pink_vampire> you need sugar.
[07:11:56] <Loetmichel> <- just had a big dish of doner kebap with french fries
[07:12:14] <Loetmichel> no sugar needs
[07:12:34] <Loetmichel> but a bit of a dark corner for some hours would be good to digest that :-)
[07:14:12] <Loetmichel> sadly i am the production manager here,,, and one of only 5 ppl at the company atm... me missing would be obvious fast
[07:15:37] <pink_vampire> after large meal the body take energy to digest the food - this is what you feel sleepy after the meal, sugar give almost instant energy to the body - this way you can avoid the sleepiness after the meal
[07:17:06] <pink_vampire> what =why way=how
[07:17:15] <pink_vampire> I need to sleep..
[07:17:25] <pink_vampire> 7:54AM
[09:38:59] <membiblio> Good Morning (east coast usa) Everyone - LinuxCNC 2.7pre does not run at all for me - is there anything I can do to get log files or other info to someone to help work out the kinks?
[09:41:50] <CaptHindsight> membiblio: what doesn't run? pastebin is good for posting log files
[09:41:53] <membiblio> I guess I will go the other route and install 2.7pre from a live dvd or from scratch from the dvd - it appears upgrading from 2.6 to 2.7 did not work for me.
[09:42:02] <membiblio> Good Morning CaptHindsight
[09:42:19] <membiblio> Do you want the debug file or should I just go the dvd install from scratch route?
[09:42:34] <CaptHindsight> greetings and salutations
[09:42:45] <CaptHindsight> what exactly is the problem?
[09:44:04] <membiblio> When upgrading from 2.6 to 2.7 it starts to launch, brings up the manual toolchanger dialog, axis loads momentarily and then exits immediately.
[09:45:22] <membiblio> Is there a 2.7pre dvd iso image available? I thought I saw one but now I don't/
[09:46:11] <cradek> membiblio: there is an error message on stderr or in dmesg. you need to share those with us. start with this: dmesg|nopaste
[09:49:28] <membiblio> cradek: I have the linuxcnc log window that opens when linuxcnc fails to load properly - there are no pertinent messaged in dmesg - do you want the linuxcnc window?
[09:49:51] <cradek> sure, pastebin that stuff
[09:49:54] <cradek> the error is in there somewhere
[09:50:15] <cradek> sometimes it's hard to spot
[09:51:25] <membiblio> cradek - I can post what I have but considering there are no new messages since boot it is unlikely yes?
[09:52:10] <cradek> if linuxcnc got that far, I don't see how there can be nothing at all in dmesg
[09:52:20] <cradek> maybe you need to tell us more
[09:52:45] <cradek> are you using the uspace or rtai build?
[09:53:00] <cradek> maybe say more about what you did to get this upgrade
[09:56:04] <membiblio> Here is the error log: http://pastebin.com/KJFGWS5S
[09:56:29] <membiblio> I am using the 2.7pre real time
[09:57:17] <membiblio> What I did to upgrade is follow the instructions on Section 4 Updating LinuxCNC on linuxcnc.org / docs / 2.7 / html / getting started
[09:57:37] <cradek> python: swrast/s_renderbuffer.c:588: map_attachment: Assertion `srb->Map' failed.
[09:58:33] <membiblio> Like I said - that is in the linuxcnc logfile - not dmesg
[09:58:36] <cradek> did you also change anything about video/opengl?
[09:59:31] <membiblio> See the top of my pastebin: Fresh install of 2.6, updated, apt 2.7 selected, updated, install 2.7 per instructions on linuxcnc.org docs 2.7 html getting started
[09:59:50] <cradek> did you run 2.6 and it worked?
[09:59:51] <membiblio> Is there a 2.7 image anywhere ?
[09:59:56] <membiblio> Yes 2.6 worked.
[10:00:19] <cradek> 2.6 worked on this fresh install, and then you updated to 2.7 and changed nothing else, and 2.7 fails with this error?
[10:00:33] <membiblio> Never mind - the getting started page has a link to the 2.7 image
[10:00:45] <membiblio> cradek - yes that is correct.
[10:01:05] <cradek> hm, that's very surprising
[10:01:30] <membiblio> cradek - if it will help I can pull this hd, install another and continue with my day - that will preserve this issue for investigation when you ask. Is this desired or not necessary?
[10:02:14] <cradek> http://forum.kodi.tv/showthread.php?tid=150605
[10:02:35] <cradek> this is a problem with opengl that is triggered by many programs
[10:02:46] <cradek> http://www.openfoam.org/mantisbt/view.php?id=733
[10:03:21] <cradek> http://psha.org.ru/irc/%23emc/2014-11-19.html#03:08:16
[10:03:47] <zeeshan> looks like opengl related?
[10:04:02] <membiblio> cradek - forget all that - this should work out of the box
[10:04:05] <cradek> yes certainly is opengl
[10:04:21] <zeeshan> membiblio: are you complaining about a free program? :)
[10:04:29] <membiblio> If you all don't need any diagnostics from this drive I will simply write over it.
[10:04:32] <zeeshan> and about something that has nothing to do with linuxcnc?
[10:04:42] <zeeshan> and rather a newer library?
[10:04:46] <zeeshan> related to graphics..
[10:04:47] <cradek> in that last conversation, he suspected another package update that came along with linuxcnc is actually what broke it
[10:05:38] <cradek> unfortunately he didn't report back to say what it was
[10:05:44] <membiblio> Again: If you don't need this diagnostic information please say so and I will wipe the drive or I can save it to help you identify a issue. Please choose save or wipe so I can help you help others.
[10:06:08] * zeeshan loves the attitude
[10:06:15] <zeeshan> cradek, did you see my video on rigid tapping
[10:06:19] <zeeshan> it works sooooooooo much better now!
[10:06:20] <membiblio> zeeshan: can you read my mind?
[10:06:30] <cradek> would you pastebin /var/log/dpkg.log please
[10:06:36] <cradek> zeeshan: yay! but no I didn't see it
[10:06:41] <membiblio> cradek: yes
[10:06:56] <zeeshan> https://www.youtube.com/watch?v=O8zq2KTam-Y
[10:06:59] <zeeshan> no external resistor
[10:07:02] <zeeshan> just internal resistor of the vfd
[10:07:23] <zeeshan> i basically have 2 deceleration rates -> below 20hz it decels in 1s
[10:07:34] <zeeshan> and above 20hz it decels in 3.5s
[10:07:44] <zeeshan> now it overshoots 20 thou consistently
[10:07:49] <cradek> beautiful
[10:07:57] <zeeshan> also swapping from modbus was the major thing that bring about consistency of overshoot
[10:07:58] <cradek> looks like it reverses in about 1 turn
[10:08:00] <zeeshan> so you were correct about that
[10:08:44] <zeeshan> im just using modbus for diagnostic information now :P
[10:09:00] <cradek> are you using analog for speed command?
[10:09:04] <zeeshan> yes
[10:09:06] <zeeshan> and also run command
[10:09:09] <zeeshan> (dio)
[10:09:31] <cradek> yeah that's sure going to be more responsive... the new command gets to it in a ms
[10:09:57] <cradek> funny to see you tap air with a shell mill
[10:10:00] <zeeshan> hahaha
[10:10:12] <cradek> it'll probably reverse even faster with a lighter "tap"
[10:10:27] <zeeshan> yes some friction added should help i'd think
[10:10:48] <zeeshan> problem is if i try to decrease the decel time to 0.2 s from 1s
[10:10:50] <zeeshan> i get following errors
[10:10:55] <zeeshan> cause i think my Z axis can't keep up
[10:11:04] <zeeshan> i've maxed out all my accel rates for my servos
[10:11:09] <zeeshan> and removed 10% for safety buffer
[10:11:22] <zeeshan> and itll still do that for pitches > 2mm
[10:11:31] <pcw_home> You need a bigger Z drive :-)
[10:11:41] <zeeshan> yessir
[10:11:54] <cradek> it looks really responsive
[10:11:57] <archivist> it is a heavy lump to move
[10:12:15] <zeeshan> so i learned how you tune max accel and max velocity
[10:12:16] <cradek> beautiful: https://www.youtube.com/watch?v=d4O_nOclcAs
[10:12:31] <zeeshan> you just keep increasing it till you see in halscope that your ferror goes crazy
[10:13:31] <zeeshan> for velocity -- you'll get a large steady state error even though your axis was tuned before
[10:14:23] <zeeshan> that lathe is sexy
[10:15:03] <zeeshan> pcw_home: i just had to do it to understand why you were saying dc injection wont work
[10:15:08] <zeeshan> cause the Z can't follow that fast! :P
[10:15:46] <cradek> chnc can turn its turret both ways I guess
[10:17:10] <archivist> must go and be nosey and look at robs toys
[10:18:03] <zeeshan> who needs a lathe
[10:18:06] <zeeshan> when you can do this:
[10:18:07] <zeeshan> https://www.youtube.com/watch?v=n6IUhros2HE
[10:18:07] <zeeshan> hahah
[10:18:19] <zeeshan> that is impressive
[10:20:08] <zeeshan> this might be a little too indepth question
[10:20:17] <zeeshan> and also a lazy one
[10:20:45] <zeeshan> but what is the fundamental difference between ethercat and modbus/profilobus etc which allows ethercat to be realtime
[10:20:48] <zeeshan> and the others to be not
[10:20:51] <archivist> did you see that fleabay Item I pointed you at?
[10:20:55] <zeeshan> NO
[10:20:59] <zeeshan> maybe i was disconnected
[10:21:00] <archivist> zeeshan|2, this is near you fleabay 190808002823
[10:21:11] <archivist> but all mine :)
[10:21:19] <zeeshan> dude
[10:21:23] <zeeshan> thats like 15 min from me
[10:21:24] <zeeshan> haha
[10:21:30] <zeeshan> and ive been to that place
[10:21:45] <zeeshan> they usually overcharge a lot for their stuff
[10:21:51] <zeeshan> is that priced right? im not familiar
[10:22:26] <archivist> dunno, depends how often it has been crashed into
[10:22:40] <zeeshan> archivist: what is special about that?
[10:22:48] <zeeshan> i've seen something like this used on fixture plates
[10:22:48] <Jymmmm> Mornin Folks!
[10:22:49] <zeeshan> to locate them
[10:23:02] <zeeshan> usually there are 3 of these balls
[10:23:13] <archivist> also used to set up your measuring probes calibration
[10:25:44] <archivist> so any dents scratches marks and its not worth anything really
[10:27:51] <archivist> so I may use http://www.renishaw.com/shop/Product.aspx?Product=A-5000-7814 or similar screwed to a bar
[10:28:15] <archivist> just for experimenting
[10:29:45] <Jymmmm> $400 USD for half a ball?! WTH
[10:30:00] <pcw_home> Ethercat has good real time because
[10:30:02] <pcw_home> 1. its on a dedicated link
[10:30:03] <pcw_home> 2. It has a real time driver
[10:30:05] <pcw_home> 2. is uses Ethernet in a different way very much like token ring so each slave gets the (single) packet
[10:30:06] <pcw_home> and extracts the slaves specific data portion of the packet and inserts its reply data in real time into that packet
[10:30:42] <Jymmmm> pcw_home: (the last one is funny =)
[10:30:47] <pcw_home> Ethernet power link can outperform Ethercat on 1G nets though
[10:31:30] <pcw_home> (without resorting to closed IP on the laves)
[10:31:49] <Jymmm> Does ethercat use IP?
[10:33:02] <pcw_home> closed source IP
[10:33:40] <Jymmm> Eh, most dont realize TCP/IP has a 40% overhead
[10:39:10] <cpresser> Jymmm: 40% tcp-header is 128bits, ip-header 20 bytes. thats less then 40% on a ~1500 bytes packet
[10:43:38] <SpeedEvil> cpresser: you have a bit/byte confusion
[10:44:50] <zeeshan> pcw_home: it looks like profilobus io does realtime control too. 1ms response time
[10:45:03] <zeeshan> im trying to figure out the physical difference
[10:45:23] <zeeshan> regarding dedicated link -- aren't all fieldbuses on a dedicated link too? theres 2 wires going between each device
[10:45:41] <pcw_home> http://www.cnczone.com/forums/newly-posted-classifieds-listings/279580-cnc.html
[10:45:43] <pcw_home> looks like a heck of a router for $3800
[10:45:50] <zeeshan> 2. real time driver -- is this a physical hardware limitation or software topology or both?
[10:46:09] <pcw_home> classic profibus is RS-485
[10:46:25] <pcw_home> (IICRC)
[10:46:28] <zeeshan> yes
[10:47:03] <zeeshan> wow that is CHEAP
[10:47:06] <zeeshan> for what you're getting
[10:47:12] <cradek> wow look at those servos
[10:47:18] <zeeshan> they are HUGE
[10:47:18] <zeeshan> lol
[10:47:25] <zeeshan> look at the main drive motor
[10:48:14] <pcw_home> I suspect even the modbus interface could be close to realtime if the drives had decent firmware
[10:48:29] <zeeshan> pcw_home: so you're saying its a hardware limitation
[10:48:33] <zeeshan> im reading some articles
[10:48:44] <zeeshan> where basically what im getting is that the communication topology is 1 reason for realtime
[10:48:56] <zeeshan> you allow only a certain time for packets to be transmitted
[10:49:08] <zeeshan> and that can only be done with proper hardware
[10:49:55] <pcw_home> I think its more firmware design where they didn't care about performance
[10:50:31] <zeeshan> so it's software side design that limits it :P
[10:50:52] <pcw_home> mostly (especially at higher baud rates)
[10:50:59] <zeeshan> it's like mach vs linuxcnc
[10:51:00] <zeeshan> :-)
[10:52:05] <pcw_home> I shoudl figure out how to do modus via the 7I77s expansion connnector
[10:52:37] <zeeshan> im kinda upset with modbus right now
[10:52:48] <zeeshan> considering how slow it was for controlling the vfd vs analog
[10:53:08] <zeeshan> but im almost positive it's due to the time() function
[10:53:17] <pcw_home> some of that is probably the userland driver
[10:53:20] <zeeshan> and the fact that userspace python components aren't realtime
[10:53:38] <zeeshan> its well over a 150 ms to 400 ms variation
[10:53:47] <zeeshan> sometimes depending on the weather
[10:53:50] <zeeshan> it might it a whole second
[10:53:53] <zeeshan> *hit
[10:53:59] <pcw_home> A all HAL comp driver with timing done in servothread chunks might be better
[10:54:13] <zeeshan> which really goes to show that it is dependent on what im doing on the computer
[10:54:24] <zeeshan> yes
[10:54:52] <pcw_home> (a customer _really _ wanted this for our Ethernet FPGA cards to avoid a separate cable from the PC)
[10:55:19] <zeeshan> it does simplify wiring a lot
[10:55:24] <zeeshan> i have 3 vfd's connected over 2 wires
[10:55:34] <zeeshan> imagine if i had to run analog to all of them
[10:55:39] <zeeshan> it'd be a wiring nightmare
[10:55:52] <zeeshan> you'd have like 2 wires for analog that really need to be shielded
[10:56:01] <pcw_home> I suspect I would need to add the right parity option to the packet UART
[10:56:11] <zeeshan> then you have depending on the vfd, 2-3 wires for digital io for start/run/rev
[10:56:13] <zeeshan> etc
[10:56:55] <pcw_home> The packet UART can do the proper timeouts automatically in hardware for high speed RTU
[10:57:12] <pcw_home> (settable in bit times)
[10:58:05] <zeeshan> how confident are you that the slave devices
[10:58:08] <zeeshan> will response quickly enough?
[10:58:31] <CaptHindsight> I propose to make an amendment to require all IRC questions to be played in the form of 20 Questions :)
[10:58:37] <pcw_home> none really...
[10:58:45] <zeeshan> so you could be sending a signal really fast
[10:58:49] <zeeshan> and not getting a response fast enough
[10:58:53] <zeeshan> and there would be lag
[10:59:13] <zeeshan> CaptHindsight: it is a conversation :P
[10:59:24] <zeeshan> if it came in question form, you'd use a forum
[10:59:34] <CaptHindsight> why? :)
[10:59:43] <zeeshan> which is why i use forums a bit less
[10:59:47] <pcw_home> yeah, I dont have any feel for how fast the VFDs are
[11:00:16] <zeeshan> i really suspect if they've got only modbus rtu and ascii option they are slow
[11:00:32] <zeeshan> some vfds give you an option for profilobus but this option usually is $$$$$
[11:00:50] <pcw_home> a scope might tell you
[11:01:15] <zeeshan> when i get around to buying a scope to diagnose my index signal scale stuff
[11:01:17] <zeeshan> i'll look into this
[11:01:32] <zeeshan> using analog is so caveman :P
[11:01:43] <CaptHindsight> for some reason my new Debian 8 install with Linuxcnc doesn't support sound over HDMI on my 3rd monitor. Who is going to fix this? :)
[11:01:57] <cradek> nobody here
[11:02:02] <CaptHindsight> lol
[11:02:08] <cradek> we might snark about it though
[11:02:33] <pcw_home> in any case it would be good if the FPGA cards could support modbus (slow or fast) just from a wiring standpoint
[11:02:34] <cradek> like this: since when did monitors have sound? what is this a TV studio?
[11:02:44] <zeeshan> yes pcw_home
[11:02:47] <zeeshan> it woulda helped me
[11:03:04] <zeeshan> you save on a rs232 to rs485 converter
[11:03:08] <zeeshan> and your wiring is also cleaner
[11:03:36] <zeeshan> for a lot of people, they keep their computer motherboard in a seperate case
[11:03:38] <zeeshan> so they'
[11:03:43] <zeeshan> so it REALLY cleans up wiring a lot
[11:03:59] <zeeshan> you only have 1 parallel cable going from comp to 7i77 for example
[11:04:11] <zeeshan> it'd be worth doing it in my opinion
[11:04:35] <pcw_home> The customer that asked uses a standard boxed PC and a USB-485 adapter (which people regularly unplug)
[11:04:47] <zeeshan> haha
[11:10:25] <Tom_itx> zeeshan are you using analog now instead of modbus?
[11:10:30] <zeeshan> yessir
[11:10:53] <zeeshan> i still have modbus connected
[11:11:01] <Tom_itx> why?
[11:11:01] <zeeshan> im getting all my torque info, temp etc from it
[11:23:02] <archivist> a mystery item http://www.ebay.co.uk/itm/CMM-Modular-Fixture-Gage-Ball-Setup-Inspection-Measuring-Tooling-Sphere-Point-/291186628097
[11:30:36] <Jymmm> cpresser: Simple enough... On a one gig line, transfer a file and measure how long it takes =)
[11:30:58] <Jymmm> like an ISO file
[11:33:53] <cpresser> Jymmm: that also depends on the layer5-7 application. its not just tcp
[11:37:36] <cpresser> Jymmm: http://pastebin.com/qFLzQ45z
[11:38:07] <cpresser> thats way less than 40% overhead. more like 6%
[11:38:38] <cpresser> plus: one of the machines used is 12years old, newer PCs might yield better results
[11:40:45] <Jymmm> cpresser: Just move 10GB woth of files from one machine to another and see how long it takes, basically something practical.
[11:41:45] <Jymmm> worth*
[11:41:57] <cpresser> Jymmm: yes, that will take longer. because disk-io and stuff also takes time
[11:42:03] <cpresser> but that is _not_ a TCP or IP problem
[11:42:45] <Jymmm> Fine, make a ramdisk, I don't really care to be honest.
[11:44:35] <cpresser> to much effort. iperf does measure the tcp throughput, no need to build another testsuite
[11:46:10] <zeeshan> PETE!!
[11:47:16] <Tom_itx> repeat
[11:47:34] <PetefromTn_> heh whats up man
[11:48:06] <PetefromTn_> just got back from the race shop with another Tig job ;)
[11:48:38] <zeeshan> http://i.imgur.com/hiXMUBM.jpg
[11:48:42] <zeeshan> look at how consistent this guy is
[11:48:42] <zeeshan> lol
[11:48:46] <PetefromTn_> still have not received the damn Tee fitting so I can put my back purge reg on the damn tank
[11:48:51] <zeeshan> though fillet welds are pretty easy to make look nice
[11:49:01] <zeeshan> damn
[11:49:15] <PetefromTn_> all I see is a cracked crankshaft
[11:49:21] <zeeshan> er
[11:49:27] <zeeshan> http://i1283.photobucket.com/albums/a544/Fabchild/11217521_915108608545192_4390638357685124682_n_zps7exfuhrn.jpg
[11:49:44] <zeeshan> but more importantly
[11:49:50] <PetefromTn_> ooh I like that pyrex cup
[11:49:53] <zeeshan> i wanted to show you another pic which i think you can appreciate
[11:49:59] <zeeshan> because you know how hard it is!
[11:50:16] <zeeshan> so it's one thing to get your bead consistent
[11:50:19] <zeeshan> check this shit out
[11:50:19] <zeeshan> lol
[11:50:23] <PetefromTn_> they ordered me a big ol aluminum block to do the T3t4 flanges on
[11:50:33] <zeeshan> PetefromTn_:
[11:50:36] <zeeshan> prepare for this
[11:50:42] <zeeshan> might blow up your screen
[11:50:47] <PetefromTn_> ROFL
[11:50:59] <zeeshan> https://twistedsifter.files.wordpress.com/2015/08/welds-by-scott-raabe-7.jpg?w=640&h=622
[11:51:03] <zeeshan> https://twistedsifter.files.wordpress.com/2015/08/welds-by-scott-raabe-6.jpg?w=640&h=632
[11:51:13] <zeeshan> this guy not only stitched the weld consistently
[11:51:17] <PetefromTn_> nice weave
[11:51:18] <zeeshan> look at the damn color around the weld
[11:51:21] <zeeshan> it's consistent
[11:51:25] <PetefromTn_> walking the cup
[11:51:38] <zeeshan> !!!
[11:51:49] <PetefromTn_> yeah that is about perfection
[11:51:58] <zeeshan> mine are never rings like that
[11:52:16] <zeeshan> theyres squiggly rings :)
[11:52:25] <PetefromTn_> I hear ya
[11:52:36] <Tom_itx> robotic tig
[11:52:38] <Tom_itx> :D
[11:52:47] <zeeshan> nahh that is done by "scott raabe"
[11:52:50] <zeeshan> all hand stuff
[11:52:51] <zeeshan> crazy.
[11:53:10] <PetefromTn_> I got a LOT of practicing to do
[11:53:47] <PetefromTn_> I am really kind of excited about the idea of making this stuff for them it will basically force me to up my game and build my skills
[11:54:03] <zeeshan> it's awesome to get paid while learning :)
[11:54:09] <membiblio> cradek and capthindsight - the same exact thing happens with a clean install of 2.7pre sbr->Map failed on a python error line
[11:54:09] <zeeshan> well not really learning
[11:54:10] <PetefromTn_> most of the welding work I get is hey man can you weld this bumper or fix my trailer hitch LOL
[11:54:12] <zeeshan> but practicing
[11:54:14] <Tom_itx> wonder why he did that one twice
[11:54:34] <zeeshan> Tom_itx: prolly not needed
[11:54:42] <zeeshan> that type of weld is just a show off weld
[11:54:44] <zeeshan> to show off how good you are
[11:54:56] <PetefromTn_> wonder what his surface prep is on that stainless around the sides
[11:55:05] <archivist> the right much
[11:55:15] <archivist> +- nuffin
[11:55:30] <zeeshan> since i know i can't be ever like this guy
[11:55:35] <zeeshan> i really need a 6 axis robot
[11:55:41] <PetefromTn_> why can't you?
[11:55:42] <zeeshan> :-)
[11:55:54] <archivist> I could moan about the two blues not matching
[11:55:57] <zeeshan> i don't have the motivation to be honest
[11:56:03] <zeeshan> im more functional than looks
[11:56:09] <zeeshan> the very first one posted
[11:56:16] <zeeshan> that's the best for me in my opinion
[11:56:24] <zeeshan> that's something i can do
[11:56:46] <zeeshan> i've tried walking the cup
[11:56:51] <zeeshan> i'm absolutely shit at it
[11:57:20] <PetefromTn_> it takes some practice to be sure to get the movement right
[11:57:30] <PetefromTn_> I am not that great at it either
[11:57:38] <zeeshan> my mucles don't understand walking the cup
[11:57:39] <PetefromTn_> but it sure makes consistency a bit easier
[11:57:40] <zeeshan> is wha ti'm saying
[11:57:45] <archivist> when you get good you can get certificates and good wages, but stuck in one trade for the rest of your life
[11:57:59] <PetefromTn_> not me
[11:58:05] <zeeshan> it's like.. yes you can play football
[11:58:16] <zeeshan> but are you going to be in the nhl?
[11:58:19] <PetefromTn_> I am wanting to be able to machine parts, tig weld parts, anodize parts, you name it LOL
[11:58:24] <zeeshan> i know my limitations :P
[11:58:42] <archivist> jack of all trades master of none
[11:58:44] <zeeshan> im the same way pete , i like to do it all
[11:58:50] <PetefromTn_> if there is one thing I have learned along the way in all of this
[11:58:55] <zeeshan> i want to engineer, design, manufacture
[11:59:09] <zeeshan> if i do this at work , or at home shop
[11:59:10] <zeeshan> im happy
[11:59:22] <PetefromTn_> it is that the guys that are really good at something have just managed to find ways to make it easy for themselves and learned the tricks of it
[11:59:38] <archivist> make stuff, takes stuff to bits, learn, play
[11:59:40] <PetefromTn_> none of this is rocket science
[11:59:50] <zeeshan> i agree with you
[11:59:55] <zeeshan> but you gotta give respect where deserved
[12:00:04] <zeeshan> some of these guys are just good
[12:00:05] <PetefromTn_> but it certainly takes some tricks and things that make the impossible look easy
[12:00:12] <PetefromTn_> Oh for sure
[12:00:13] <archivist> they just dont do much else but what they are good at
[12:00:18] <zeeshan> archivist: exactly
[12:00:21] <PetefromTn_> like that Toxicfab guy is amazing
[12:01:06] <PetefromTn_> it comes down to how much time and effort you are willing to put into it..
[12:01:20] <zeeshan> PetefromTn_: i got this one buddy whos into race cars
[12:01:20] <archivist> I think I prefer to be an all rounder than a specialist
[12:01:26] <zeeshan> he's been tigging for 5 years
[12:01:32] <PetefromTn_> when I first started machining parts I would not want to even post pics of the stuff it was so bad..
[12:01:32] <zeeshan> his welds look nothing like yours
[12:01:44] <zeeshan> you're are top notch
[12:01:54] <zeeshan> his are all over the plate
[12:02:00] <PetefromTn_> No they are not but I appreciate the kind words
[12:02:08] <PetefromTn_> I have a LONG way to go here
[12:02:21] <PetefromTn_> but I am just starting with this tube stainless welding really
[12:02:23] <zeeshan> http://www.meyette.us/HeaderPipePracticeTIG.jpg
[12:02:29] <zeeshan> his welds look like the middle top
[12:02:34] <zeeshan> they get the job done though
[12:02:51] <zeeshan> cause he sands and polishes them up
[12:02:55] <zeeshan> and you cant even tell :P
[12:03:27] <PetefromTn_> I must say that after using the .030 mig wire the other night I was amazed at how much easier it was to control the puddle
[12:03:32] <archivist> I see a gaps at the ends
[12:03:33] <membiblio> Here is the dialog box output from the linuxcnc 'fail to launch' window: http://pastebin.com/CMC4WjVm
[12:03:50] <zeeshan> membiblio: cradek pointed out the error that's causing it
[12:03:57] <zeeshan> python: swrast/s_renderbuffer.c:588: map_attachment: Assertion `srb->Map' failed.
[12:04:07] <zeeshan> it is something to do with your opengl drivers
[12:04:08] <archivist> same as before
[12:04:08] <zeeshan> not linuxcnc
[12:04:12] <membiblio> zeeshan it is not my responsibility to fix the iso so knock it the hell off
[12:04:27] <zeeshan> lol
[12:04:29] <membiblio> I am posting so the developers can fix their release
[12:04:32] <Tom_itx> the iso worked fine for me
[12:04:34] <archivist> no it is your older hardware and an opengl bug
[12:04:41] <Tom_itx> xactly
[12:04:47] <membiblio> It did not work fine for me and the developers asked for feedback
[12:04:51] <zeeshan> membiblio: if you're going to be a dick about it
[12:04:56] <zeeshan> no ones going to give a shit about helping you
[12:05:03] <membiblio> zeeshan: again read my mind please.
[12:05:17] <PetefromTn_> Zeeshan I just got a bunch of free rod from them some ER308l .045 and ER309L .045
[12:05:28] <PetefromTn_> looking forward to getting some of this stuff going
[12:05:39] <zeeshan> you got 309l that thin?
[12:05:41] <zeeshan> nice!
[12:05:45] <zeeshan> i dont have any
[12:05:49] <zeeshan> i can't find that easily
[12:05:51] <PetefromTn_> the photo you posted of that pyrex cup is that yours?
[12:05:55] <zeeshan> no
[12:05:57] <zeeshan> thats some other guy
[12:05:59] <zeeshan> haha
[12:06:03] <PetefromTn_> I REALLY like that setup
[12:06:07] <zeeshan> i'm not spending 80bux on that cup
[12:06:09] <PetefromTn_> any idea what it is
[12:06:10] <zeeshan> :P
[12:06:27] <PetefromTn_> its not just the cup it is the shortness and quick release etc.
[12:06:31] <zeeshan> http://weldmongerstore.com/products/furick-fupa-12-tig-cup-kit
[12:07:03] <zeeshan> it wont work on my torch
[12:07:04] <PetefromTn_> what does the kit slide onto tho?
[12:07:04] <zeeshan> or yours
[12:07:13] <zeeshan> maybe there exists one for #17
[12:07:26] <PetefromTn_> I like my 17 tho
[12:08:35] <zeeshan> i'm not sure what it slides onto
[12:08:37] <zeeshan> never sed
[12:08:39] <zeeshan> used

[12:09:28] <zeeshan> when i can buy a pyrex dish from the store
[12:09:29] <zeeshan> for $10
[12:09:41] <Tom_itx> If you own a #17, #18, or 26 torch your going to need an adaptor kit
[12:09:42] <zeeshan> i have a hard time paying F60 for a piece of glass and some viton o-rings
[12:09:43] <zeeshan> haha
[12:09:47] <zeeshan> $60+_
[12:10:08] <PetefromTn_> looks like it'll be a hundred total
[12:10:16] <PetefromTn_> plus shipping
[12:10:20] <zeeshan> have you broken ceramic c ups
[12:10:22] <PetefromTn_> but that is for 2 cups
[12:10:23] <zeeshan> mine just break randomly
[12:10:26] <zeeshan> without even dropping
[12:10:27] <PetefromTn_> yeah I have
[12:10:30] <zeeshan> especially welding aluminum
[12:10:34] <PetefromTn_> dropping and overheating LOL
[12:10:37] <zeeshan> if that happens do this
[12:10:39] <zeeshan> id cry
[12:10:42] <zeeshan> do = to
[12:11:05] <SpeedEvil> pyrex?
[12:11:13] <SpeedEvil> that does not seem up to the task
[12:11:19] <PetefromTn_> I like that furick cup
[12:11:36] <PetefromTn_> I like the fact that you can see thru it most of all
[12:11:47] <Tom_itx> now we're discussing cup sizes...
[12:11:56] <PetefromTn_> LOL
[12:12:01] <zeeshan> SpeedEvil: you'd think that
[12:12:07] <zeeshan> but its being used as we speak :)
[12:12:09] <PetefromTn_> I guess I am a size 12!!
[12:13:05] <SpeedEvil> I guess if you don't touch molten metal with it
[12:13:38] <zeeshan> that's what the titanium protector is
[12:13:39] <zeeshan> for
[12:13:50] <zeeshan> so when youre walking the cup, and touching hot metal, it prolly doesnt destroy it
[12:14:05] <SpeedEvil> http://www.ebay.co.uk/itm/kanger-subtank-plus-pyrex-glass-tube-/252032975411?pt=LH_DefaultDomain_3&hash=item3aae560233
[12:14:08] <zeeshan> but weld-molten metal solidifies pretty quickly
[12:14:20] <zeeshan> SpeedEvil: exactly man
[12:14:27] <zeeshan> i have a hard time justifying the cost for a consumable like that
[12:14:36] <zeeshan> when you know it's a cheap material
[12:14:59] <SpeedEvil> yeah
[12:15:19] <archivist> probably find the local welding supplies shop has them dirt cheap
[12:15:23] <PetefromTn_> I didn't think it was that bad when you consider you get two plus the o-rings and all the hardware...
[12:15:24] <zeeshan> no
[12:15:31] <zeeshan> they haven't hard of this stuff
[12:15:36] <archivist> yet
[12:15:37] <zeeshan> none of my local ones at least archivist
[12:15:43] <zeeshan> these have been around for a decade
[12:15:48] <PetefromTn_> mine don't have it either
[12:15:54] <zeeshan> only used by top fabricators
[12:16:03] <PetefromTn_> I had a hard time getting ceramic cups from them LOL
[12:16:27] <PetefromTn_> OH cool that means if I buy em I become a top fabricator!! WIN

[12:26:47] <PetefromTn_> when are you picking it up hehe
[12:27:07] <zeeshan> honestly
[12:27:12] <zeeshan> i'd sell my drill press for that machine
[12:27:13] <zeeshan> that looks sweet
[12:27:18] <archivist> I need a new (to me ) car as well
[12:27:58] <archivist> very odd looking spindle/motor combination
[12:28:12] <PetefromTn_> when I was over at the race shop a truck arrived with a sick cool black RX7 with a 3 rotor motor in it... I drooled a little
[12:29:34] <mozmck1> I'm having an odd problem with probing.
[12:30:24] <mozmck1> Probe runs down until it touches, and then I get an error saying the probe input is already active at the start of a probing move.
[12:30:42] <mozmck1> But it is not, and the probing move had already moved about .5 inch
[12:31:59] <mozmck1> this is 2.7.0~pre7
[12:32:49] <zeeshan> nice PetefromTn_
[12:33:24] <zeeshan> mozmck1: how are you determining it's not active?
[12:34:34] <mozmck1> LED on probe, probe move goes .5 inch and stops when probe input goes active, etc.
[12:35:05] <mozmck1> I tried inverting the probe signal to test and I get the error as soon as the probe move tries to start.
[12:35:23] <zeeshan> reason i ask is
[12:35:28] <zeeshan> maybe its a noise spike?
[12:35:44] <zeeshan> which you can pick up in halscope
[12:36:24] <mozmck1> Don't know. Once a probe move is in progress, I think if the probe input goes active it should see it as a contact and stop - not give a false error?
[12:36:50] <mozmck1> So in other words, a noise spike may cause it to complete the move prematurely, but that should be all I would think.
[12:37:01] <archivist> noise is often a problem with switches and contacts
[12:37:03] <PetefromTn_> jeez that damn Tee fitting apparently is not coming today either... just checked the mail
[12:37:55] <zeeshan> mozmck1: i'd actually monitor the pin in halscope
[12:38:02] <zeeshan> to get a better idea of what is going on
[12:38:05] <zeeshan> rather than relying on the led
[12:38:14] <zeeshan> cause the led is correct yes, but the controller might be seeing something else
[12:39:44] <Tom_itx> hmm
[12:41:22] <Tom_itx> an idea i had.. how can i use a momentary switch to toggle a subroutine to call an M3 or M5 based on whether the spindle is on or off
[12:41:40] <Tom_itx> that sounds pretty doable
[12:42:39] <jdh> I got 6 SS tees a few mins ago
[12:43:00] * zeeshan slaps jdh
[12:43:08] <Tom_itx> goin golfing?
[12:44:06] <jdh> waiting on some SS crosses though. 1/4" tubing
[12:44:15] <zeeshan> anyone who's milled hard wood before
[12:44:19] <zeeshan> is it like milling a hard plastic?
[12:44:29] <Tom_itx> it's like milling hardwood
[12:44:35] <zeeshan> in terms of the feel you get when you turn the handles
[12:44:35] <jdh> retrofit helium plumbing for welding
[12:44:53] <zeeshan> jdh where did you get your T's from
[12:44:55] <Tom_itx> not much feel to it
[12:45:00] <Jymmm> zeeshan: no
[12:45:09] <zeeshan> Jymmm: what does it feel like
[12:45:11] <zeeshan> aluminum?
[12:45:18] <Tom_itx> less pressure
[12:45:31] <Jymmm> zeeshan: due to the grain of the wood it can vary
[12:45:40] <zeeshan> Jymmm: assume its uniformly hard
[12:45:40] <zeeshan> :P
[12:45:46] <zeeshan> like a massive knot inthe wood
[12:45:53] <jdh> msc. crosses from mcmaster
[12:46:07] <zeeshan> jdh: http://www.acestainless.com/
[12:46:12] <zeeshan> i don't know if you know of them
[12:46:14] <zeeshan> but they are super cheap
[12:46:15] <Jymmm> zeeshan: ha, a knot is a knot, no getting around the bitch factor there =)
[12:46:45] <zeeshan> http://www.aceraceparts.com/weld-els/304l-stainless-weld-els/stainless-weld-tees/stainless-weld-tees-schedule-40/weld-els-tee-s40
[12:46:46] <zeeshan> pretty cheap
[12:46:48] <Jymmm> zeeshan: think more like grainy tool steel =)
[12:47:07] <jdh> z: they have none
[12:47:15] <zeeshan> jdh ah
[12:47:28] <Tom_itx> http://www.wood-database.com/wood-articles/top-ten-hardest-woods/
[12:47:29] <zeeshan> Jymmm: you're really telling me wood is like machiniing tool steel?
[12:47:40] <jdh> wood sucks
[12:47:59] <SpeedEvil> Wood is stiffer than steel.
[12:48:03] <SpeedEvil> (by some metrics)
[12:48:10] <zeeshan> jeez here we go again
[12:48:11] <zeeshan> lol
[12:48:12] <Jymmm> zeeshan: Well, aluminum is gummyish, wood has a grain so denisty is going to vary
[12:48:25] <zeeshan> ill try to rephrase
[12:48:41] <jdh> and varies with orientation
[12:48:54] <zeeshan> i knowwwwwww
[12:48:55] <zeeshan> damn it
[12:49:00] <zeeshan> i'm saying assuming worse case scenario
[12:49:10] <Jymmm> zeeshan: Also, if you are doing anything artistic (carving) you'll need to be more autely aware of the grain or you'll get lots of crap results
[12:49:10] <zeeshan> is it anywhere close to aluminum
[12:49:11] <archivist> you can get orientation variation in metals too
[12:49:12] <zeeshan> or much softer
[12:49:12] <SpeedEvil> It catches fire.
[12:49:15] <Tom_itx> it's brutal if you hit a knot
[12:49:26] <zeeshan> Tom_itx: yes
[12:49:31] <zeeshan> but still like machining aluminum?
[12:49:34] <Tom_itx> no
[12:49:39] <Jymmm> zeeshan: soft steel
[12:49:39] <zeeshan> it should be softer yea?
[12:49:39] <Tom_itx> it's like machining wood
[12:50:23] <Jymmm> zeeshan: askign the same question 5 different ways is not going to change the answer you want to hear =)
[12:50:29] <zeeshan> it's easy
[12:50:33] <zeeshan> someone whos machined aluminum and wood
[12:50:38] <PetefromTn_> its easy to machine man you are making way too much of it.. the laminated wood is dense
[12:50:42] <zeeshan> they must have a feel if a knot is harder to machine than machining aluminum
[12:50:47] <Jymmm> zeeshan: NO, wood is not liek aluminum
[12:50:52] <zeeshan> is it worse?
[12:50:55] <zeeshan> or it better?
[12:51:01] <archivist> different
[12:51:02] <Jymmm> zeeshan: wait, wood, or a knot in wood?
[12:51:04] <Tom_itx> i've machined hardrock maple and beech and it's just not that difficult
[12:51:06] <zeeshan> PetefromTn_: i'm trying to get a feel for it
[12:51:12] <zeeshan> relative to materials ive machined
[12:51:22] <zeeshan> cause i wanna cut this crap as fast as i can
[12:51:24] <Jymmm> zeeshan: a knot is a mother fucker, period
[12:51:36] <zeeshan> like i know if i got a tooth pick 1/8 end mill burried .25" in steel
[12:51:40] <jdh> try some samples
[12:51:40] <zeeshan> and im going at 20ipm
[12:51:40] <Tom_itx> zeeshan, you need different tool angles
[12:51:43] <zeeshan> im prolly going to snap it
[12:51:46] <PetefromTn_> most of these laminated woods don't have knots since they are slided thin
[12:51:59] <zeeshan> i need the same feel for wood
[12:52:14] <Jymmm> zeeshan: try some as jdh suggested
[12:52:23] <zeeshan> ofcourse im gonna try some
[12:52:29] <zeeshan> i wanted to save myself the headache and get a starting point
[12:52:30] <zeeshan> :)
[12:52:40] <zeeshan> thank you for nothing guys!!
[12:52:41] <Jymmm> zeeshan: then quit yur bitchn and jsut GIT ER DONE! =)
[12:52:42] * zeeshan pouts
[12:53:07] * Jymmm gives zeeshan a kick in the assets for good luck and motivation!
[12:53:33] <Tom_itx> zeeshan, this is what you're looking for: http://www.onsrud.com/plusdocs/Doc/index.html?model.code=FeedSpeeds
[12:53:49] <zeeshan> https://pure.ltu.se/portal/files/60618115/Luis_Cristovao.pdf
[12:53:50] <zeeshan> page 29
[12:53:55] <zeeshan> okay
[12:53:58] <zeeshan> wood is NOTHING like aluminum
[12:54:02] <zeeshan> look at those cutting forces
[12:54:11] <Tom_itx> no
[12:54:22] <zeeshan> Tom_itx: i came across that page
[12:54:26] <zeeshan> didnt really have anything about forces
[12:54:33] <zeeshan> im more trying to figure out deflections and things like that
[12:54:42] <zeeshan> need the force for it
[12:55:42] * Jymmm sets mode /forcnickchange zeeshan luke_skywalker
[12:55:51] <Tom_itx> https://www.ncsu.edu/bioresources/BioRes_06/BioRes_06_4_3687_Porankiewicz_AGM_Main_Norm_Cut_Forces_Wood_1402.pdf
[12:56:13] <Tom_itx> there's some math fer ya
[12:58:00] <Tom_itx> http://www.fao.org/docrep/ARTICLE/WFC/XII/0886-A2.HTM
[12:59:02] <zeeshan> hehe
[12:59:06] <zeeshan> damn these guys giving chip thickness
[12:59:16] <zeeshan> that's actually the proper way to measure forces
[12:59:29] <zeeshan> cause who cares if you're turning or milling
[12:59:41] <zeeshan> chip thickness is stays constant between the two operations for 2 sets of conditions
[12:59:50] <Tom_itx> i don't even care if you're turning or milling wood OR aluminum
[12:59:53] <PetefromTn_> not all wood is the same so doubt that will help you too much really
[13:00:03] <zeeshan> PetefromTn_: it gives a feel for it
[13:00:07] <zeeshan> i have 0 feel right now
[13:00:09] <zeeshan> and i dont have a manual machine
[13:00:15] <zeeshan> so i cant go get a feel for it either
[13:00:19] <zeeshan> ill have to go by sound and eye
[13:00:27] <zeeshan> which doesn't really give a good feel for force
[13:00:45] <zeeshan> one test i can do is take aluminum
[13:00:52] <PetefromTn_> honestly I would machine it at what I would call a conservative aluminum rate
[13:00:56] <zeeshan> and lathe tool bit
[13:01:06] <zeeshan> and a piec eof wood and try to scrap the surface of both
[13:01:08] <zeeshan> and see what it feels like
[13:01:11] <PetefromTn_> you don't want to go ripping thru or you will get too much heat
[13:01:21] <zeeshan> well heat i was gonna control with sfm
[13:01:23] <PetefromTn_> it cuts easily with sharp HSS tooling
[13:01:27] <zeeshan> but iwanna feed the shit out of it
[13:01:28] <zeeshan> if i can
[13:01:31] <zeeshan> without snapping the bit
[13:01:45] <PetefromTn_> ok
[13:01:50] <zeeshan> like basically what im saying is
[13:02:11] <zeeshan> that article online says for 1/8 end mill you can feed around 0.005 ipt
[13:02:24] <zeeshan> in steel id prolly snap the end mill
[13:02:48] <zeeshan> im hoping i can do .015 ipt
[13:03:08] <zeeshan> at the end of the day if i can machine this thing at 2500 rpm and 80 ipm
[13:03:10] <zeeshan> im happy
[13:03:24] <zeeshan> cause right now my starting values are 2500 rpm and 25 ipm
[13:03:34] <zeeshan> for a 1/8" end mill
[13:03:36] <PetefromTn_> 2500?
[13:03:36] <zeeshan> does that sound right?
[13:03:40] <zeeshan> yes
[13:03:41] <PetefromTn_> hell no
[13:03:48] <PetefromTn_> I would spin it much faster than that
[13:04:01] <PetefromTn_> probably as fast as possible for the machine
[13:04:08] <zeeshan> that'd be 3150rpm
[13:04:13] <PetefromTn_> wood working tools typically spin really fast
[13:04:20] <PetefromTn_> Oh okay
[13:04:22] <zeeshan> but i can also attach an external spindle
[13:04:25] <zeeshan> and run 20,000 rpm
[13:04:31] <PetefromTn_> yeah spin it for all its worth and feed appropriately
[13:04:45] <zeeshan> im really thinking of buying a 20,000 rpm china spindle
[13:04:53] <PetefromTn_> if you are gonna be making a LOT of parts then that would probably be a better idea
[13:04:55] <zeeshan> and making a bracket for my mill
[13:05:06] <zeeshan> i have these 4 m12x1.75 bolt holts on the square head
[13:05:08] <Jymmm> zeeshan: http://goo.gl/8HTYOZ
[13:05:14] <PetefromTn_> but the problem with that is you can burn the parts too then and you will need wood specific mills
[13:05:22] <zeeshan> wher ei can attach it to.. and then using it for engraving and wood jobs
[13:05:41] <PetefromTn_> I did the same thing
[13:06:01] <PetefromTn_> I machined a heavy mount plate for a router or engraver head for the VMC since I only have 6k RPM spindle
[13:06:09] <zeeshan> excellent
[13:06:12] <zeeshan> did you use a china spindle
[13:06:13] <PetefromTn_> so far I only used it once tho
[13:06:21] <zeeshan> with er collets
[13:06:22] <PetefromTn_> no I machined it to fit my porter cable router
[13:06:42] <PetefromTn_> but I am sure it could be made to do either they are probably similar diameters
[13:07:17] <PetefromTn_> my spindle face has a labrynth seal plate on the bottom that bolts on with like six heavy bolts
[13:07:34] <PetefromTn_> I use those to attach it and machined it to fit the bottom of the labrynth seal face
[13:07:47] <zeeshan> nice
[13:07:57] <zeeshan> router is an excellent suggestion
[13:08:02] <zeeshan> cause they're meant to be used with wood
[13:08:10] <zeeshan> and im sure it'll be fine for engraving too
[13:08:13] <zeeshan> and i can buy it locally!
[13:08:18] <PetefromTn_> yeah it engraves pretty good
[13:08:31] <zeeshan> can it handle 1/8 and 1/4 shanks?
[13:08:54] <Jymmm> good luck on the 1/8th
[13:09:07] <PetefromTn_> I use the Porter Cable http://g-ecx.images-amazon.com/images/G/01/th/content_26/Q4_2010/c26-B0000DCBK0-1-s.jpg
[13:09:16] <PetefromTn_> yeah it comes with both 1/4 and 1/8 collets
[13:09:19] <jdh> you can buy low runout adapters
[13:09:26] <PetefromTn_> or rather 1/2 and 1/4
[13:09:35] <PetefromTn_> but they sell adapters
[13:09:47] <PetefromTn_> they even sell some sort of quick change setup now
[13:09:56] <PetefromTn_> supposed to have decent repeatability
[13:09:59] <Jymmm> Most are crap 1/4 to 1/8 so be sure what you are getting
[13:10:02] <PetefromTn_> but I don't have that
[13:10:53] <Jymmm> I have 1/4, 3/8 and 1/2 collets
[13:11:08] <zeeshan> okay so just need 1/8 tools
[13:11:11] <zeeshan> with 1/4 shank
[13:11:29] <Jymmm> zeeshan: just curious, what 1/8 tools do you need?
[13:11:44] <zeeshan> some engraving tools i have are 1/8 shank
[13:11:54] <Jymmm> for wood?
[13:12:01] <zeeshan> no for metal
[13:12:02] <zeeshan> they are carbide
[13:12:17] <Jymmm> Hmmm, okey
[13:12:33] <jdh> what are you making?
[13:12:33] <zeeshan> i assume wood cuts better
[13:12:44] <zeeshan> with very large positive rake tools
[13:12:54] <PetefromTn_> are you gonna be making the venus demilo's?
[13:12:58] <zeeshan> yessir
[13:13:03] <zeeshan> i gotta start doing something next week
[13:13:03] <PetefromTn_> nice
[13:13:06] <jdh> wood can leave really fuzzy edges
[13:13:13] <zeeshan> jdh this is stablized wood
[13:13:14] <PetefromTn_> are you getting a rotary fixture?
[13:13:16] <zeeshan> its not supposed to do that
[13:13:19] <Jymmm> LOTS AND LOTS of fuzzy edges =)
[13:13:22] <zeeshan> PetefromTn_: im thinking about it
[13:13:29] <zeeshan> im trying to justify the cost of a high speed spindle
[13:13:30] <zeeshan> and rotary axis
[13:13:34] <zeeshan> vs the job at hand
[13:13:38] <zeeshan> both are things i want for myself
[13:13:45] <PetefromTn_> surely a bunch of those babies would score you a rotary or fourth..
[13:13:55] <zeeshan> but do they make sense to get right now for this job depends on once i get a price set in stone with him
[13:14:10] <zeeshan> right now we are in a big range
[13:14:14] <PetefromTn_> tell you gotta order at least 1225558882225568 of them
[13:14:20] <zeeshan> he's promised me 40 orders
[13:14:22] <Jymmm> zeeshan: Just check the return policy before buying anything =)
[13:14:30] <zeeshan> and there is a 90% c hance of 40 more every month for 6 months
[13:14:31] <archivist> slow speed, fuzzies, very high speed the wood is hammered and does not get time to bend out the way
[13:14:41] <zeeshan> but anything with chance i take lightly
[13:14:46] <zeeshan> so im not factoring that in the cost
[13:14:59] <PetefromTn_> make sure you get at least half up front
[13:15:10] <Jymmm> what PetefromTn_ said
[13:15:11] <zeeshan> yea i did 50% for design
[13:15:17] <zeeshan> and 50% upon compleition
[13:15:27] <zeeshan> same goes for manufacturing
[13:15:34] <PetefromTn_> good luck man sounds like an interesting project
[13:15:57] <zeeshan> PetefromTn_: actually since we're talkking about this
[13:16:00] <zeeshan> lemme show you something
[13:16:01] <Jymmm> zeeshan: For wood fuzzys, you can clean up using green scotchbright pad
[13:16:23] <zeeshan> actually ill show you in a bit once i get something sorted
[13:16:33] <zeeshan> Jymmm: he fully expects fuzzies
[13:16:36] <PetefromTn_> just called around local for that damn tee fitting.. I can get one for $65.00!!!
[13:16:38] <zeeshan> and will be hand finishing himself
[13:16:45] <Jymmm> zeeshan: ah
[13:16:59] <jdh> pete: what ends?
[13:17:04] <PetefromTn_> that laminated wood cuts pretty good and does not fuzz too much just at the top of the cuts
[13:17:16] <PetefromTn_> jdh ?
[13:17:22] <zeeshan> jdh you're confusing his t's
[13:17:24] <zeeshan> with regular t's
[13:17:25] <zeeshan> haha
[13:17:42] <PetefromTn_> http://www.ebay.com/itm/191547352277?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[13:17:45] <zeeshan> he's looking for a cg580
[13:17:46] <zeeshan> t
[13:17:48] <PetefromTn_> that is what I need
[13:17:50] <archivist> is it t time yet
[13:18:13] <PetefromTn_> already have one coming here but I got a part they need done by tomorrow here
[13:18:25] <jdh> heh. I have lots of those also
[13:18:48] <zeeshan> jdh really?
[13:18:51] <PetefromTn_> of course you do
[13:18:52] <zeeshan> what do you guys use those for?
[13:19:01] <jdh> but, I have the 580 run in to a ss npt T
[13:19:09] <zeeshan> PetefromTn_: if you fusion weld the tube
[13:19:11] <zeeshan> youll be okay!!
[13:19:13] <zeeshan> no need for backpurge
[13:19:14] <jdh> helium
[13:19:26] <PetefromTn_> it's mild steel to stainless flange
[13:19:27] <zeeshan> for diving?
[13:19:32] <jdh> yeah
[13:19:36] <zeeshan> PetefromTn_: doh hehe
[13:19:49] <jdh> I have a 4 bottle helium cascade
[13:19:57] <PetefromTn_> I can't believe these bastards are taking this long to ship
[13:20:10] <jdh> all Teed together
[13:20:15] <PetefromTn_> I ordered the damn flow reg the same night and it has been here for a day or two now
[13:22:18] <PetefromTn_> Well I am gonna go play with my tig welder a bit...
[13:22:21] <PetefromTn_> bbl
[13:29:41] <jdh> We tossed a 580 manifild a few months ago. all the parts were 580, even the pigtails were 580 on each end
[13:31:37] <zeeshan> you should send anything being tossed my way
[13:31:39] <zeeshan> if youre not going to use it :)
[13:31:50] <shogunx> ok, so a bit of digging later... i have found an arm board with a mini-pcie slot, and a parallel port card for said mini-pcie slot. what other hurdles do i face in running a cnc mill from an arm based linux host via linuxcnc?
[13:33:23] <shogunx> iMX.6 with 4 1ghz cores plus 2 gigs of memory should be enough for the job. are there special patches that need be applied to the kernel for rtai, or just modules enabled?
[13:33:34] <shogunx> ^^enabled/compiled
[13:38:39] <SpeedEvil> Any specific reason why an arm board?
[13:38:42] <Jymmm> zeeshan: jdh is a tease... he talks about a lot of neat toys that are being tossed out =)
[13:38:52] <Jymmm> SpeedEvil: leg boards are too expensive?
[13:39:08] <Jymmm> /smartass
[13:40:01] <shogunx> ARM because everything here is ARM... rack, desktops, etc. power draw savings, primarily, plus size could lead to direct integration.
[13:41:31] <shogunx> i am running on an off-grid solar power supply here... every watt counts. then there is the issue of the power draw of the mill itself, and how that can be improved by making it native DC operation, but that is a problem for a different day.
[13:42:03] <SpeedEvil> your average cheap I3 board wants 12W ish
[13:42:04] <Jymmm> shogunx: chipmunk powered!!!
[13:42:47] <Jymmm> shogunx: there is a DC intel mobo
[13:42:56] <cradek> shogunx: the only answer possible is we don't know what problems you will encounter
[13:44:48] <archivist> although some arm related bugs were found/fixed recently, needs more volunteers :)
[13:44:52] <shogunx> yeah, i avoid intel like the plague. mini-box has dc-dc atx supplies, so you can convert any board... that is not the challenge. intel based boards use WAY more power.
[13:45:21] <shogunx> so... there are folks who have successfully ported to ARM?
[13:47:39] <shogunx> linux on these ARM's is no challenge... just wondering if there are x86 specific assembly instructions or similar gotchas in the emc code
[13:47:48] <jdh> I would take them home myself if I could get them out
[13:48:02] <shogunx> if that compile has been done already, then my gut instinct says no.
[13:48:34] <furrywolf> does linuxcnc even use any inline asm?
[13:48:40] <archivist> it is the realtime kernel that may be a problem http://permalink.gmane.org/gmane.linux.distributions.emc.devel/14849
[13:49:28] <furrywolf> if you're worried about the power your cnc machine's control draws, you need a bigger cnc machine. :P
[13:51:52] <shogunx> archivist, in this post jeff mentions non-realtime mode?
[13:54:04] <shogunx> looks like rtai.org indicates support for ARM7 based hosts.
[14:00:36] <shogunx> i am worried about the power everything draws, btw. the days of seemingly limitless cheap energy out of the wall are coming to a close.
[14:02:01] <furrywolf> as someone with an off-grid solar system, I too worry about power usage. And yet I know that my control's power draw is trivial compared to the rest of the machine. I have 1.5hp of spindle and 750W of stepper power supply, I'm not worry about the 20W the laptop I'm using to drive it draws.
[14:03:17] <shogunx> sounds like you are using this for more serious cnc work than i would. my primary goal is to be able to print circuit boards from copper clad.
[14:04:55] <shogunx> secondary goal is to do so in as power efficient a manner as possible.
[14:08:19] <shogunx> like i said... stepwise. 5-7W for the control system, and then we will see about those motors.
[14:08:40] <archivist> basic principle still applies, a moving machine can easily use more energy than the control
[14:09:03] <archivist> the effort to save a penny
[14:09:05] <furrywolf> I measure every single watt I draw, and I don't have " limitless cheap energy out of the wall", but I still don't worry about the x86 laptop using more power than an arm laptop. :P
[14:09:10] <shogunx> very true. same applies to the hotend of a 3d printer.
[14:09:31] <furrywolf> FX port 1, inv 1.0A, chg 0.0A, buy 0.0A, sell 0.0A, load 1.0A, in 0.0V, out 123.0V, batt 24.4V, mode 2, ac 0, error 0x00, warning 0x00, misc 0x08.
[14:09:31] <furrywolf> MX port 2, chg 7.0A, pv 0.0A, batt 24.4V, pv 29.0V, daily 0.0kWh 9999.0Ah, aux 0, error 0x00, charger 2.
[14:09:31] <furrywolf> FN port 3, A -5.2A (enabled), B 0.0A (disabled), C 0.0A (disabled), batt 24.2V, btemp 99.0C, SOC 48.0%, flags 0x08, extra id 3, data 0.00.
[14:11:19] <shogunx> batteries are pretty low there. i get worried when my 12V L-16 array dips to 12.4, but then again, those cells are almost 9 years old.
[14:11:20] <Rab> shogunx, considered Machinekit on BeagleBone Black?
[14:11:41] <furrywolf> not a lot of sun lately.
[14:12:04] <shogunx> furrywolf, you will be interested in this: electrodacus.com
[14:12:16] <Rab> Graphics performance isn't good, so AXIS GUI is sluggish. But might be a good fit for your simple application, with very low power consumption.
[14:13:13] <furrywolf> shogunx: yes, you're right. if I were rich, I'd be quite interested in li* batteries.
[14:13:23] <shogunx> Rab... thanks. i will check it out. at worst we can ssh -X into the box from something with better graphics performance. better to, actually, since you lose the overhead on the gui.
[14:14:20] <Rab> shogunx, I tried X forwarding and saw no performance improvement. It really only affects the toolpath preview.
[14:14:51] <shogunx> check out what open hardware developer Dacian Todea has to say there. These batteries are cheaper over the life of the system. Just for when it becomes replacement time for you, or on the chance you have customers who want off grid solar as well.
[14:15:28] <shogunx> Rab, so, like with pronterface, you can generally just ignore that part of the gui output.
[14:15:38] <furrywolf> right now I have some mostly-toasted lead-acid batteries. my future plans are to replace the electrolyte in the 40 300Ah NiFe cells I got used and see how they work.
[14:15:45] <Rab> shogunx, sure. There are other available GUIs as well.
[14:16:23] <shogunx> those NiFe's should last FOREVER.
[14:17:23] <furrywolf> should. :P
[14:17:40] <furrywolf> however, their ongoing cost is quite a lot higher than the sellers want you to believe.
[14:18:02] <furrywolf> every 8-12 years they need an electrolyte change, to the tune for $1000 for the cells I got. and that's if you buy your chemicals direct from chemical suppliers and mix everything yourself.
[14:18:49] <furrywolf> the cells I bought are russian (kursk accumulator) from the '80s, were used until the mid '90s, stopped working, then sat idle.
[14:19:32] <furrywolf> http://fw.bushytails.net/battsinvan01.jpg transporting them here
[14:20:14] <SpeedEvil> furrywolf: I wonder if you can skip that.
[14:20:23] <SpeedEvil> furrywolf: put them in a nitrogen filled box
[14:20:43] <furrywolf> there's three different models of cells there, although all with the same capacity... apparantly the guy I got them from bought 20, liked them, then went to buy 20 more, but they didn't have more, so gave him ten and ten of what they did have...
[14:21:17] <furrywolf> the box would be a hydrogen and oxygen filled bomb pretty quickly. :)
[14:21:40] <furrywolf> they gas a lot at full charge. they're pretty efficient up to 50% charge with minimal gassing, then gas heavily over that.
[14:22:25] <shogunx> personally, i think graphene ultracaps can fill this gap, cheaper, too.
[14:22:32] <furrywolf> what gap?
[14:22:41] <SpeedEvil> http://www.enercotek.fi/ext/cms3/attachments/midac-mcp-catalyst-plugs.pdf oooh
[14:22:55] <SpeedEvil> Interesting first paragraph
[14:22:57] <shogunx> energy storage
[14:23:27] <furrywolf> and even the best ultracaps are still stupidly expensive and rather large for their capacity. Maxwell's best are the size of soda cans and store about as much as a nicd AA... and, of course, need much more complex electronics, since their voltage steadily falls, not holds due to the chemical properties.
[14:23:28] <shogunx> without the upkeep, smaller, and cheaper. cheap enough for mass manufacture and deployment anyway.
[14:23:59] <furrywolf> also, maxwell's caps are failing at the 10-20 year mark, which they weren't supposed to do.
[14:24:03] <shogunx> i have some of those 2600F 2.5V caps. i am talking about a different animal than that, brought about by superior materials manufacturing.
[14:24:33] <furrywolf> how many do you have, and how much do you want to sell them for? :P
[14:24:49] <SpeedEvil> shogunx: and the newer ones presumably also say they won't fail at the 10-20 year mark
[14:25:01] <shogunx> i have 10 of them, 8 are in use.
[14:25:17] * furrywolf needs 14 of them
[14:25:23] * furrywolf is not rich. :(
[14:26:47] <furrywolf> I wonder what would happen if I put some trays of KOH around the vents in the battery box? would it absorb significant amounts of co2 rather than letting it get to the cells?
[14:27:03] <shogunx> i am not rich either, just a shrewd master scavenger
[14:27:17] <furrywolf> not much to scavenge around here
[14:30:06] <shogunx> https://www.youtube.com/watch?v=6acygQLg-HM
[14:35:18] <shogunx> how does machinekit on beaglebone physically interface with the mill?
[14:35:39] <furrywolf> bbl
[14:36:15] <shogunx> gpio?
[14:36:51] <shogunx> oh, i see. expansion board. nevermind.
[14:57:58] <PetefromTn_> that was a very interesting video
[16:28:48] <Wolf_> ^.^ this channel sure is quiet at times...
[16:32:01] <XXCoder> yeah
[16:33:02] <Wolf_> I has some shiny things, UPS came late as hell, usually here at 10-11am, got here at 4:45pm
[16:34:01] <Wolf_> http://i.imgur.com/KKqnJah.jpg just missing stepper kit and loads of build time lol
[16:35:43] <XXCoder> nice
[16:36:33] <Wolf_> The not so shiny turd all the parts are going on http://i.imgur.com/6NvwkBz.jpg (and the z-axis air spring counter balance
[16:37:18] <fenn> try polishing it to make it shinier
[16:38:05] <Wolf_> buy index mill, chuck X1 up in it, polish ?
[16:38:36] <fenn> just get one of those sheepskin buffers
[16:38:36] <XXCoder> attach polishing disk to spindle and use it to polish surface lol
[16:39:25] <Wolf_> ick sheep skin
[16:40:16] <Wolf_> dual-action with hex buffing pads http://i.imgur.com/e4EqRjF.jpg, after http://i.imgur.com/dSWm6zY.jpg
[16:40:30] <Wolf_> but I don’t think it will help that X1 any
[16:42:19] <Wolf_> I do have to say that it was a neat surprise to open the mcmaster box and see ruland couplers
[16:58:54] <Wolf_> and they looked a lot bigger on my 20” monitor in the cad drawings lol
[17:00:28] <andypugh> I have a project that needs 23 of these: http://www.ebay.co.uk/itm/Glows-Non-Stop-For-Decades-Large-Tritium-Isotopes-50mmx3mm-Marker-Lights-big-/261999073162?hash=item3d005c978a
[17:01:02] <andypugh> I think I need to find a cheaper source :-)
[17:01:58] <Tom_itx> not your average glow stick?
[17:02:10] <Wolf_> wow 50mmX3mm, I didn’t know they made them that big
[17:02:24] <andypugh> There are some 60m ones on there too.
[17:02:38] <andypugh> Tom_itx: That depends what you consider “typical”
[17:04:09] <Rab> They tore down a local movie theater many years ago, the exit signs were all illuminated by those tritium tubes.
[17:04:30] <Rab> My friends took a few. Not sure where they ended up.
[17:04:43] <andypugh> They are probably nearly dead by now anyway?
[17:05:02] <Rab> Yeah, they were pretty dim at the time.
[17:09:44] <andypugh> Wolf_: 80mm… http://www.aliexpress.com/store/product/Automatic-light-15-years-Giant-tritium-tube-beta-5-mm-80-mm-tritium-gas-lamps-Survival/1661092_32276481461.html
[17:10:31] <DaViruz> finally, a good source of tritium for my fusion bomb.
[17:10:41] <PetefromTn_> woah someone is giving away a hardinge AHC lathe non working in maryland for FREE
[17:10:42] <Rab> Material Type: Titanium
[17:10:50] <Wolf_> wut
[17:10:52] <DaViruz> andypugh: did you get that motor sorted?
[17:11:00] <malcom2073> PetefromTn_: Where?
[17:11:05] <Wolf_> where…
[17:11:21] <malcom2073> PetefromTn_: More info! :P
[17:11:26] <andypugh> DaViruz: Which motor?
[17:11:31] <PetefromTn_> https://www.facebook.com/photo.php?fbid=1609880379264161&set=pcb.918357258234411&type=1&theater dunno if that link works
[17:11:42] <malcom2073> Doens't work
[17:11:42] <DaViruz> the one with the circular connection thingy.
[17:11:52] <andypugh> I think the answer must be “yes” as all my motors now work. I have three lathes capable of spinning.
[17:12:08] <PetefromTn_> https://www.facebook.com/groups/772213566182115/
[17:12:35] <malcom2073> I'll have to join that group, my dad is a member already haha
[17:12:39] <PetefromTn_> might have to join the group
[17:12:51] <DaViruz> maybe it wasn't yours? oh well
[17:12:53] <andypugh> Someone has the wrong end of the stick: “Tritium gas is what we might call "mildly radioactive." Its half life is 12.36 years – much, much less than the over 1600 years half life of radium, a highly radioactive material that had been used on watch dials and hands over half a century ago”
[17:12:57] <PetefromTn_> but yeah it is in maryland just north of DC apparenlty
[17:13:06] <malcom2073> Nice! less than 2 hours from me
[17:13:12] <Rab> andypugh, haha
[17:13:14] <PetefromTn_> call em
[17:13:16] <Wolf_> 15-20mins from me
[17:13:18] <PetefromTn_> or email em
[17:13:29] <PetefromTn_> can you see the pics?
[17:13:35] <malcom2073> I can't
[17:13:50] <Wolf_> and I have a rollback parked in my yard right now
[17:13:58] <malcom2073> Bah heh
[17:14:20] <Wolf_> but, I don’t really need a lathe, I think...
[17:14:38] <PetefromTn_> http://i.imgur.com/mTTtrEh.jpg
[17:14:40] <malcom2073> Wanna rent out a rollback?
[17:15:02] <Wolf_> doesn’t have valid tags on it….
[17:15:07] <malcom2073> heh
[17:15:14] <malcom2073> C'mon, it's MD. Not old enough for historic?
[17:15:15] <Wolf_> whats that machine weight?
[17:15:27] <PetefromTn_> http://i.imgur.com/7n9x63s.jpg
[17:15:41] <malcom2073> Gotta be upwards of 3klbs
[17:15:49] <Wolf_> thats it?
[17:16:04] <Wolf_> hell, could put it in the bed of my truck then
[17:16:15] <PetefromTn_> i'd say 3-4k yeah
[17:16:47] <malcom2073> Yeah, an ebay listing for one says 3000lbs
[17:16:51] <PetefromTn_> https://www.facebook.com/tobyjim.zastrow?fref=ufi owner
[17:16:53] <Wolf_> let me guess, who ever gets it is responsible for removal/rigging?
[17:17:03] <PetefromTn_> well yeah
[17:17:13] <malcom2073> Sometimes you just can't give away a machine
[17:17:21] <malcom2073> I got my mill off a guy who was gonna call in a scrapper to removei t heh
[17:17:27] <PetefromTn_> if I could afford the gas and had a truck I would already be on my way there LOL"
[17:17:51] <Wolf_> if I knew I could get it on my truck..
[17:18:26] <Wolf_> but my forklift is down too so getting it back off the truck may be a pain in the ass
[17:18:51] <malcom2073> HEh
[17:18:56] <malcom2073> Why is all your stuff down?
[17:19:03] <malcom2073> Now that I know you're so close, I may bug you to be for hire :-P
[17:19:14] <Wolf_> lol
[17:19:39] <Wolf_> free junk, forklift ran, but needed a starter, water pump and ring gear
[17:19:48] <andypugh> I love this old switchgear. https://picasaweb.google.com/lh/photo/FSCzw8MPFguMZa6-mpDYmNMTjNZETYmyPJy0liipFm0?feat=directlink
[17:20:02] <Wolf_> have all the parts, just need to put it back together
[17:20:04] <andypugh> But it takes up so much space: https://picasaweb.google.com/lh/photo/g-cVqOqkk7uWFs-tDvGv-9MTjNZETYmyPJy0liipFm0?feat=directlink
[17:20:11] <Wolf_> rollback isn’t mine
[17:20:31] <andypugh> I amticipate putting a PC motherboard where one of the rectifiers is…
[17:20:42] <malcom2073> HEh those resistors
[17:20:54] <malcom2073> Or are they rectifiers?
[17:20:56] <andypugh> Not resistors, Selenium Rectifiers
[17:21:00] <malcom2073> Oh nice
[17:21:06] <malcom2073> Pretty high wattage then I'd assume
[17:21:08] <malcom2073> ?
[17:21:13] <andypugh> No
[17:21:29] <PetefromTn_> guy just said he can load it
[17:21:40] <malcom2073> Oh man heh
[17:21:43] <malcom2073> I have a trailer that can haul it
[17:22:09] <PetefromTn_> get on there and contact him man its free!! shit even if it was toast you could probably part it for good money
[17:22:57] <andypugh> malcom2073: The transformer output to the biggest recifier says “100VA”
[17:23:02] <malcom2073> haha
[17:23:08] <Deejay> gn8
[17:23:17] <malcom2073> There's another AHC chucker for sale nearby for like $500 fully tooledand working
[17:23:17] <Wolf_> I would get it but I have no idea where to start with something like that lol
[17:24:14] <PetefromTn_> WAT
[17:24:27] <PetefromTn_> fully tooled and working for $500????
[17:24:33] <malcom2073> So my dad just told me
[17:24:51] <CaptHindsight> get 2
[17:24:53] <PetefromTn_> do you have any idea what tooling costs for a lathe like that?
[17:25:02] <malcom2073> called him about that free one lol
[17:25:05] <CaptHindsight> way over $50
[17:25:23] <Wolf_> tooling for anything usually costs $$$$$
[17:26:49] <Wolf_> half the reason I ended up w/ this POS X1 and 7x10 china freight lathe, used but came with most everything to get started and then some
[17:28:40] <andypugh> Wierd, I can’t get to the Tormach website
[17:29:10] <PetefromTn_> maybe they've shut you out andy in their bid to take over the world!
[17:31:43] <malcom2073> lol
[17:40:22] <malcom2073> Man that lathe is temping
[17:40:30] <malcom2073> but I'd really rather avoid sticking machines in my barn until I concrete it :/
[17:41:19] <Wolf_> I would pick it up but I have no idea what I would do with it, plus I’m low on space as well
[17:41:24] <malcom2073> Lol
[17:41:35] <malcom2073> I still need to sell my lathe and motorcycle, then I'll have some room
[17:45:11] <PetefromTn_> i think someone is gonna get it already
[17:45:30] <malcom2073> Yeah
[17:45:35] <malcom2073> Good for them
[17:45:44] <malcom2073> What's the chucker anyway? Is it CNC?
[17:46:58] <malcom2073> Ohhh, cool, they're barely pre cnc
[17:48:14] <Wolf_> oh well, enough break time, back to making chips :)
[17:48:22] <malcom2073> Yowch, that's way more work than it's worth it to me
[17:48:26] <malcom2073> I should go make chips
[18:13:07] <pink_vampire> good evening (morning)
[18:19:01] <PetefromTn_> evening
[18:35:59] <pink_vampire> hope to finish the bandsaw project today.
[18:45:04] <Tom_itx> PetefromTn_ got new pics for us?
[18:46:08] <PetefromTn_> pics of what?
[18:54:23] <PetefromTn_> http://i.imgur.com/UNjrqH7.jpg
[18:57:19] <MacGalempsy> evening
[19:13:48] <malcom2073> PetefromTn_: Haha tooling nice
[19:14:10] <malcom2073> I did some reading into what the AHC does, sounds like a pure production machine
[19:20:14] <Wolf_> pink_vampire: look what name is on the couplers http://i.imgur.com/KKqnJah.jpg
[19:41:37] <shogunx> so to sum up, and correct me if I am wrong, please... with a beaglebone black, machinekit in a prebuilt wheezy image, and a cape from xylotex, one can drive essentially any cnc mill which has a db-25 parallel interface?
[19:43:56] <PetefromTn_> not my machine hehe
[19:45:33] <shogunx> off the shelf mill w/ parallel then.
[19:53:26] <malcom2073> shogunx: That's what I do, except a 3d printer ia Gecko G540, and a PMDX cape
[19:54:09] <malcom2073> via
[19:55:53] <malcom2073> But otherwise yeah, 4 axis step/directon control with BBB, machinekit, cape
[19:55:57] <malcom2073> via DB25 interface
[20:31:51] <zeeshan> dun dun dun
[20:31:52] <zeeshan> http://imgur.com/a/EOJan
[20:31:56] <zeeshan> final design
[20:32:01] <zeeshan> what a whole lot of work.
[20:36:03] <Tom_itx> you gonna machine it?
[20:36:34] <SpeedEvil> powered from what?
[20:36:40] <SpeedEvil> Is that an 18650?
[20:37:39] * jdh ponders "drug paraphenelia manufacturing" on a resume
[20:38:00] <SpeedEvil> It's clearly for mint and lavender
[20:38:21] <jdh> uh huh
[20:49:05] <zeeshan> Tom_itx: yessir
[20:49:15] <zeeshan> hes got e-cig customers lined up already
[20:49:28] <zeeshan> i need to figure out total time to machine this
[20:49:31] <zeeshan> and give him a quote
[20:49:36] <Tom_itx> how you gonna fixture it?
[20:49:55] <zeeshan> i have some ideas
[20:50:09] <zeeshan> but it involves a coulpe of chips
[20:50:14] <zeeshan> if you look at the hidden line picture
[20:50:21] <zeeshan> assuming all the surfacing is done etc
[20:50:27] <zeeshan> now i gotta drill these crazy compound holes
[20:50:31] <zeeshan> for the wires to pass through
[20:50:37] <zeeshan> those will definitely need a jig, otherwise the setup time will be huge
[20:51:00] <zeeshan> im thinking of machining a negative split half die
